Abstract

The present invention provides an expression driving method and device, and an expression driving model training method and device. The expression driving method comprises: obtaining a first video; and inputting the first video to a pretrained expression driving model to obtain a second video, wherein the expression driving model is trained on the basis of a target sample image and a plurality of first sample images, a face image in the second video is generated on the basis of the target sample image, and posture expression features of the face image in the second video are the same as those of a face image in the first video. The expression driving method and the expression driving model training method provided by the present invention are used for improving the time relevancy of the second video.
